The bulbourethral glands, also known as Cowper glands, play a vital role in preparing the urethra for the passage of semen during ejaculation.
These pea-shaped glands secrete a clear, thick fluid that serves two primary functions:
- Lubrication: The fluid acts as a lubricant for the urethra.12
- Flushing Agent: It functions as a cleaning agent, washing out the urethra to remove any residual urine before semen is ejaculated.12
Additionally, this secretion may help create a more suitable environment for sperm survival and contribute to the consistency of the seminal fluid.12
